Maintain system health

The System Health page displays information about the Performance Center system health (including connectivity of Performance Center components and version alignment), and enables you to run a full validation on your Performance Center system. The Maintenance Tasks tab provides constant monitoring of the system's key components in order to detect system failures.

View system health

To view information about the Performance Center system health in Performance Center Administration, click Maintenance > System Health, and select the tab for the system component you want to view (Hosts, Servers, or ALM).

By default, the System Health grid displays the last known system health results for each component in your Performance Center system, including a description of the task, start and end time, task status (Passed, Failed, Warning), and task results.

Click to refresh the grid so that it displays the most up-to-date information.

Perform a system check

To run a full validation on your Performance Center system:

1. In Performance Center Administration, click Maintenance > System Health.

2. Configure the system check.

   1. Click Check System and select which Performance Center system components (ALM Platform, Performance Center servers, Performance Center hosts) to include when doing a system check.

      • For Performance Center servers and hosts, select all or the specific servers and/or hosts in the system to check.

      • For Performance hosts, you can use the search box to search the hosts list by name, and to show only those hosts that include the specified search string.

        After selecting the specific hosts in the system to check, you can click Show only selected to hide the other hosts.

      Note: The system check displays a host only if it is currently operational, in Idle state, not over firewall, and not a standalone load generator.

   2. Click Start to perform the check.

3. Click the Hosts, Servers, or ALM tab to see results of the system components that you included in the system check.

   To filter the system check results to display results that have a failed status only, select Show Only Failed Tasks.

   For details on the Performance Center servers that you selected to include in the system check, see Add a server.

   For details on the Performance Center hosts that you selected to include in the system check, see Add a host.

Create a system health report

To export the results of the system check as a Microsoft Excel worksheet, click Export to CSV .

The report is generated and the CSV file is downloaded to your browser's download directory. When the download is complete, click the file name in the status bar to open the report.

The report contains the following information for all tasks in the grid:

UI Element	Description
Component Name	The name of the component on which check task was
Description	A description of the task performed
Start Time	Start time of the task
End Time	End time of the task
Result	A detailed description of the outcome of the task
Passed	Passed or failed depending on the outcome of the task
Status	Progress of the task

Schedule automated maintenance tasks

Scheduled automated maintenance tasks provide constant monitoring of the system's key components in order to detect system failures. You use the Maintenance Tasks tab to check the status of the system.

To view information about maintenance tasks performed by the system:

1. In Performance Center Administration, click Maintenance > System Health.

2. Select the Maintenance Tasks tab.

   The following fields are available in the Maintenance Tasks tab:

   Field (A - Z)	Description
   Name	The type of maintenance check. For details, see the list below.
   Recurrence (minutes)	The frequency of the maintenance task.
   Description	A description of the maintenance task.
   State	Enabled or Disabled.
   Last Execution Time	The last time the maintenance task was executed.

3. Click the name link to view maintenance task details or to change the run frequency.

   The following table describes the maintenance tasks:

   UI Elements (A - Z)	Description
   Resource Recovery Task	Performs predefined validation tests on Controllers and load generators that are in the Non-Operational state. If the host passes the test, its status changes to Operational. Controller validation tests. Tests the OTA connection, ability to run, and available disk space. Load Generator validation tests. Tests the connection to the agent. The task parameters should be within the following guidelines: MIN_APPLICATION_DIR_DISK_SPACE: Between 10 and 1000 CHECK_LG_TIMEOUT: Between 1 and 15 MAX_RETRIES: Between 1 and 1000 Default frequency: Every 15 minutes Note: For load generators over a firewall, this is performed by the OFW Status Update task (see above).
   Result Cleaning Task	Cleans test run results from Controllers or load generators in the following instances: If the results have already been collated. There are old performance tests whose results were not collated. If the performance test was deleted. The RESULT_EXPIRY_DAYS task parameter should be between 1 and 1000. Default frequency: Every 6 hours
   OFW Status Update Task	Updates the real status (Operational or Non-Operational) of a host that is located over a firewall. Default frequency: Every 15 minutes
   Orphan Run Task	Identifies orphan test runs during and outside of the active timeslot. Default frequency: Every 15 minutes
   Data Processor Task	Sets and updates a data processing queue for any of the following actions: Analyzing a test run, recalculating the SLA, or adding test runs to a trend report. Default frequency: Every minute
   Check Host Task	Verifies the host installation, and updates the host status to either Operational or Non-Operational. Default frequency: Every 15 minutes
   Orphan PAL Reports Task	Deletes report items that are not a part of any report. Default frequency: Every 24 hours
   Publish Runs For Trending	Automatically add runs to trend reports Default frequency: Every 60 minutes
